Dona Luisa Isabel Alvarez de Toledo y Maura, Duchess of Medina-Sidonia (1936-2008), was the 21st holder of the title. She was known as the "Red Duchess" for her opposition to General Franco, although she was not a communist. She married Leonardo Gonzales de Gregorio Marti in 1955. They had three children, two sons and a daughter. On her death bed she "married" Liliana Maria Dahlmann, who had been her "secretary" for 20 years.
